Apollo 8, while we are waiting for the high gain, I will continue the trajectory summary. We can still get back to the mid-Pacific line in 146 hours from the thirteenth REV, and you are on your way after 138 seconds of the burn. That's 138 seconds, gets you clear of the butterfly region. We recommend not trying preignitions or restarts after 20 seconds. If you go beyond 20 seconds, this may get the trajectory beyond the correction—RCS correction capability to a free return. The weather in recovery area is good. We have an AOS following TEI of 89 plus 28 plus 39 and an AOS without TEI of 89 plus 37 plus 24. During the burn, you may notice a slight change in chamber pressure and tank pressures due to the fuel exhaustion in the storage tank and going to the sump tank. This may occur somewhere around 2 to 5 seconds into the burn. It'll be a small change in pressures in both systems. Going down the systems, all systems are GO. In ECS, we want to stop water boiling after TEI for trajectory purposes. Your water dump situation looks good; you should be good to greater than 105 hours. We'll try to hold off the water dump until after MCC 5. In the EPS, we'd like to stir the cryos prior to TLI—correction TEI. The next purge on the fuel cells will occur at approximately 92 hours, and that will be both hydrogen and oxygen. Your battery status: battery A 34.9, battery B 39.1, and Charlie 38.5. We have the single tank cryo capability. SPS: looking at the performance on the previous burns, you can anticipate a normal burn taking approximately 3.7 seconds in excess of the computed values. Engine performance looks nominal, and all parameters have been steady. RCS looks good; all four quads according to the computer programs have approximately the same capacity. You have a good REFSMMAT to take you through TEI. We'll have a post TEIPTC attitude for you in a few minutes. and that just about wraps up what we have on systems. Over.
